In the Linux kernel, the following vulnerability has been resolved:

idpf: check error for register_netdev() on init

Current init logic ignores the error code from register_netdev(),
which will cause WARN_ON() on attempt to unregister it, if there was one,
and there is no info for the user that the creation of the netdev failed.

WARNING: CPU: 89 PID: 6902 at net/core/dev.c:11512 unregister_netdevice_many_notify+0x211/0x1a10

Introduce an error check and log the vport number and error code.
On removal make sure to check VPORT_REG_NETDEV flag prior to calling
unregister and free on the netdev.

Add local variables for idx, vport_config and netdev for readability.
